Title: Fuel injection nozzle of diesel engine
Inventor: TAKEUCHI YASUHIRO
IPC: F02M45/00
Filed: 1982-02-09
Abstract: PURPOSE:To suppress the rate of injection at the time of low speed and low load by furnishing a passage to release part of the fuel sent from an injection pump by pressure from inside the nozzle body to outside and by blocking this passage when a needle rises exceeding a certain set position. CONSTITUTION:A gap 7 is provided in the upper part of a pressure chamber 6 situated above, and part of the fuel is sent back to the return side through this gap 7. When the fuel pressure attains the valve opening pressure for an injection nozzle, the nozzle needle 2 shifts upward, and the fuel is injected by passing the sheet part 4. Even during this period the fuel flows out through the gap 7, so that the rate of injection is suppressed. If the pressure rises further and the nozzle needle 2 goes up, the gap 7 is blocked by the nozzle needle 2, and the pressure chamber 6 is shut off from the return side. Accordingly the rate of injection sinks throughout the ranges to cause reduction of noise and NOx.
